it just to jus below 250 which is the highest mark on the oil temp but does say what the reading is in ! and when the map was done it wads mapped to 16-17 psi so maybe someone else has just turned the boost down or it has a boost leak like if its a leak from the intercooler it might restrict it anyway ? either way to only get 165 when it was mapped to 240 is a big loss originally i got the car cause thought it was just a boost leak and hed lied about a few mods didnt know it could be this much hassle
